make my photo like this

this is clip art from a CD label program but most clip art has coloration similar to this image... how would I go about turning a finished photo or artwork into a picture like this??? Many clip art has a similar color style like this picture so how would I turn a photo into something like this in Gimp???

most clip art is vector based graphics (meaning you can scale it up or down and it keeps the quality, doesn't get blurry, but only in a vector based program)

So for this effect, the easiest way is to trace your photo or artwork in Inkscape and add the gradients in either Inkscape or import it into gimp and add gradient/blend there.

Another (more or less complex) way in gimp (will need photo divided into a layer per part you want to colorize *hint)

1. Select part of the picture you want to change the color, cut & paste it as a new layer.
2. Then "Colors > Threshold" or "Colors > Posterize: 2 colors" makes it 2d cartoony/psuedo vector
3 "colors > colorize" Pick a new color

4. Repeat steps 1 through 3 with all parts of the photo you want to cartoonify

If you want a screenshot of hints on how to do this in Gimp, please update us on your last problem. You have a habbit of abandoning your past issues. See here:

A lot depends on the image. The G'mic plugin / color sketch filter can give a nice pastel effect.
You do need to play around with the settings, in this case reduce the 'edge' value
Does not break any speed records in action.

Your kidding right...? The suggestions maybe a bit wordy, but they will achieve the results your looking for Assuming you put in the work to colorize it, rich's plugin recommendation would probably even get it done automatically.

Did you even attempt to do any/all of the suggestions to compare between them?

I'll put up what my suggestion can look like(along with the others too even) if you can upload a sample landscape photo that you want to convert to the cartoon/anime art style first.
